Abstract:Precision ideological and political education refers to the use of big data to accurately grasp students’ ideological tendencies and achieve personalized ideological and political education. In this sense, big data can empower precision ideological and political education in universities through three key dimensions: precise identification of students’ ideological characteristics, targeted delivery of educational content, and accurate evaluation of pedagogical outcomes, thereby bringing revolutionary changes to ideological and political education in universities. However, this process faces practical challenges, including data imbalances, insufficient technological proficiency among teachers, and homogenized information pushed by big data algorithms. Therefore, this paper proposes some strategies such as building a data-sharing mechanism, enhancing teachers’ technical application capabilities, and optimizing algorithmic recommendation systems. These measures aims to improve the pertinence and effectiveness of ideological and political education, thereby promoting the sustainable development and innovation of precision ideological and political education in universities in the era of big data.
